Stereographic binding

I recently looked at a Victorian gift book titled 'The Rainbow',
dated 1847. It was bound in tan calf with a very beautiful gilt
design on the covers including some leather onlay.  On the bottom of
the spine was 'Patented Stereographic Binding'; I have not been able
to turn up any information on this process.  The design was very
much out of character for the 1840s. Can anyone steer me to some
information about the technique?
